Rule of 72 Calculation

The Rule of 72 equation is as follows:

( \text{Years to Double} = \frac{72}{\text{Annual Rate of Return}} )

Where the “Annual Rate of Return” is expressed as a percentage. This equation provides an estimate of the number of years it takes for an investment to double based on the given annual rate of return. Keep in mind that this formula is a simplified approximation and might not be accurate for all situations, particularly for very high or very low-interest rates.

The Rule of 72 is a simple formula used to estimate the number of years it takes for an investment to double, given a fixed annual rate of return. The formula is as follows:

Years to Double = 72 / Annual Rate of Return

Where:

• “Years to Double” is the number of years it takes for the investment to double.
• “Annual Rate of Return” is the expected annual growth rate or interest rate of the investment.

Please note that the Rule of 72 is an approximation and works best for annual rates of return between 6% and 10%. For more accurate calculations, especially with higher rates or compounding frequencies, it’s recommended to use more sophisticated financial tools or calculators.
